The effect of rule (4) on a series or parallel sequence of quantum mechanical steps is to insure that a conscious observer does not skip a step. This rule effectively places the observer in continuous contact with the system.

We criticize and generalize some properties of Nöther charges presented in a paper by V. Iyer and R. M. Wald and their application to entropy of black holes. The first law of black holes thermodynamics is proven for any gauge-natural field theory. As an application charged Kerr-Newman solutions are considered. As a further example we consider a (1 + 2) black hole solution. 1

We show that the entanglement between inner and outer particles, with respect to the event horizon, is the microscopic origin of the black hole entropy. Due to the non-unitarity of the mapping between the vacua in the flat and the curved frames, this entanglement is very robust. The holographic nature of the entropy is recovered in a quantum field theoretical setting, and it is shown that, at m...
